Mitsubishi Pajero 1991 Q&As

Check out real-world situations relating to the Mitsubishi Pajero here, particularly what our experts have to say about them.

• Engine revving highly when towing a caravan

  Even when it’s completely empty, your caravan is still likely to weigh a couple of tonnes (give or take). At which point, you’re using a fair chunk of the Pajero’s towing capacity of 2500kg. What’s happening is that the transmission of the car is choosing to shift down a gear or two to bring the engine up to a speed where it’s making enough power and torque to haul the rig along at the speed you’ve chosen to travel at. Maximum torque in the Pajero’s 3.5-litre V6 occurs at 3500rpm, so that’s what the transmission will aim for when you need maximum thrust.

  The process also takes some of the load off the transmission, helping it live longer and avoid damage and overheating. There’s a general rule that says you shouldn’t really tow anything remotely heavy with the transmission in overdrive. Experienced towers physically lock the gearbox out of overdrive, and this, essentially, is what the car is doing for you by shifting down gears when a hill or headwind increases the load on the driveline.

  The petrol V6 in the Pajero was never a fuel sipper, and I’m not surprised you’re seeing higher fuel consumption in this scenario. This is also the reason many people who regularly tow choose a turbo-diesel to do so.

• The engine in my 2009 Mitsubishi Pajero cut out suddenly

  This sounds like a classic case of a vehicle with a fuel pump that has died. Electric fuel pumps have a very finite lifespan and, when they stop, they do so suddenly, for no apparent reason and with the result that the engine will simply not start or run at all. By spraying starting fluid into the engine, you’re giving it a sniff of fuel; enough to make it fire, but not run for long.

  You’re probably looking at a new fuel pump, but don’t forget to check fuses and relays, the lines for leaks and the various fuel filters for cleanliness.

• The temperature gauge in y 2005 Mitsubishi Pajero keeps spiking

  Unless your engine is overheating very quickly and then miraculously cooling instantly, I’d say there’s a problem with either the temperature gauge itself or the sender/sensor unit that controls it.

  An auto electrician will be able to test the gauge and its sensor and tell you what’s happening. Scanning the vehicle electronically might also reveal the cause as the onboard computer may have logged this odd reading as a fault code.

• Why is the C/D lock light on my 2002 Mitsubishi Pajero coming on?

  This light is designed to warn you that you have the centre differential locked. This diff lock should only be used off-road in limited-grip situations and having the lock engaged on the bitumen will soon break expensive driveline parts. You’d also notice if the diff was engaged as the car would feel very odd to drive with lots of clunks and groans and no desire to be steered normally.

  What’s more likely is that the light itself or the sensor that triggers it has a short-circuit that is feeding the wrong information to the body computer which then lights up the warning. By shutting the engine down and restarting it, you’re effectively rebooting the body computer and things go back to normal for a while. An auto electrician would be our first stop.

  If by some chance the light is illuminating because the diff lock is, indeed, attempting to chime in, you have a more serious problem as the driveline might well suffer huge damage if the lock managed to actually engage on the highway.
